USB device not recognized, and more!

Question

This morning when I tried to sync m y Z22, I got "USB DEVICE NOT RECOGNIZED".  Connected the cable to every one of my USB ports, tried to sync each time but got the same message. 
I shut down the PC, unplugged it, waited a few minutes, reconnected it, rebooted, and tried to sync again.  Still got "USB DEVICE NOT RECOGNIZED".
Checked Palm Support, was advised to upgrade to the current version of the software (I was using V4-something).  Downloaded and installed the upgrade.  I got an error at the end of the installation that (what I assume was my old software) had been moved to Palm OS Incompatible Apps. 
I tried to sync again, same problem.  Opened the (new) software & half my data is gone.
 So, I have a few problems:
1 - How do I fix this &^#$!!! USB error? and,
2 - How do I roll-back the software to my previous version to access all my data?  In Add/Remove Programs, with Updates checked, the new software is the only one there.  (Because I couldn't sync, at least the data on my Z22 is still intact.)
Someone PLEASE help, my whole LIFE is in this thing!!!
Thanks in advance,
